Short summary
We investigate the impacts of anthropogenic water regulation on riverine DOC transport by the developed model. The results suggested that DOC transport in most rivers was mainly influenced by reservoir interception and surface water withdrawal. The impact of human water regulation on riverine DOC exports grew year by year. In general, this study developed an effective scheme to simulate DOC exports from terrestrial to aquatic systems, which is important for estimating global carbon budgets.

We implemented both urban water use schemes in a model (Weather Research and Forecasting model) and assessed their cooling effects with different amounts of water in different parts of the city (center, suburbs, and rural areas) for both road sprinkling and urban irrigation by model simulation. Then, we developed an optimization scheme to find out the optimal water use strategies for mitigating high urban temperatures.

Short summary
Short summary
Analysis of the interaction between the climate and ozone in the stratosphere is complicated by the inability of climate models to simulate the quasi-biennial oscillation (QBO) – an important climate mode in the stratosphere. We use a set of model simulations that realistically simulate QBO and a novel ozone diagnostic tool to separate temperature- and circulation-driven QBO impacts. These are important for diagnosing model–model differences in QBO–ozone responses for climate projections.

Short summary
This study discusses the changes in the summer thermal environment in the Chengdu–Chongqing urban agglomeration due to urban expansion in complex terrain conditions in the recent 40 years, using high-resolution simulations with the WRF model. We quantify the influence of a single urban expansion factor and a single complex terrain factor on the urban thermal environment. Under the joint influence of complex terrain and urban expansion, the heat island effect caused by urbanization was enhanced.
This study discusses the changes in the summer thermal environment in the Chengdu–Chongqing...
